javax.jdo.JDOUserException: The persistence capable object "Hephalant: name [Joyce] color [yellow]
snozzle length [4]" given as a parameter to the query is not yet persistent and therefore cannot be
used.

javax.jdo.JDOUserException: The column "customer_type_id" was set to
multiple different values in this SQL statement. This is probably because
the schema mapping uses a single column for multiple fields on the
assumption that the fields will always store the same underlying value,
but the assumption was broken.
